Most Police will write a report for you for harassing communications. You then give the report number to the cell phone provider to verify you have filed a report and they will do the investigative work. I'm not sure where you live, but where I work we do not investigate. We turn the info. over to the cell phone provider. Good luck.ur local police station can help with this problem tell them u have had harassing calls from that number and they will do the leg work for u
Also, the person filing the report has to be the owner of the cell phone......in your case, that would be the female you refer to. She would need to be the one filing the report, not yourself.
